Common name: Tail-barred parrotfish

Scientific name: Scarus caudofasciatus (Günther, 1862)

General information

The Redtail Parrotfish, Scarus caudofasciatus, is a vibrant and dynamic addition to any large marine aquarium. Known for their striking coloration and pronounced beak-like mouthparts, these fish play a crucial role in the health of coral reefs by grazing on algae and dead coral, which helps to prevent algal overgrowth and promote coral growth.

Juveniles exhibit different color patterns compared to adults, with the latter showcasing a red tail that gives the species its common name. They are a part of the Scaridae family, which are known for their ability to change sex from female to male as they mature, a process known as protogyny.

Care

Redtail Parrotfish require spacious tanks with plenty of live rock to mimic their natural habitat and provide grazing opportunities. They are not suitable for reef tanks as they can cause significant damage to corals and invertebrates due to their feeding habits. A varied diet that includes algae-based foods and occasional meaty offerings will keep them healthy.

Reproduction

In the wild, Scarus caudofasciatus forms harems consisting of a dominant male and several females. They are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs. Reproduction in the home aquarium is rare and challenging due to their complex social structure and large space requirements.

Habitat

Redtail Parrotfish are found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They inhabit coral reefs and lagoons, often seen grazing in shallow waters. Their presence is vital for the maintenance of reef ecosystems, as they help control algal growth and contribute to the sand production through the digestion of coral.

Geographical distribution includes areas such as the Red Sea, East Africa, the Maldives, Indonesia, northern Australia, and the central Pacific.
